TheDream.US is the largest scholarship program in the country for participants in the Obama-era Deferred Action for Childhood Arrival program (DACA), who are often called Dreamers. The scholarship helps Dreamers who might otherwise be unable to afford college. Undocumented immigrants are not eligible for federal grants or loans, and they are precluded from state aid and in-state tuition rates in many states.

“My dad came to the U.S. when he was 16 as part of Operation Pedro Pan,” Jeff Bezos said in a statement Friday. “He landed in this country alone and unable to speak English. With a lot of grit and determination – and the help of some remarkable organizations in Delaware – my dad became an outstanding citizen, and he continues to give back to the country that he feels blessed him in so many ways. MacKenzie and I are honored to be able to help today’s Dreamers by funding these scholarships.”

Candy Marshall, president of TheDream.US, called Bezos’ donation a “magnificent gift.”

“It is a shot in the arm for Dreamer students at a time when some are questioning whether they should be in the United States at all,” she said in a statement. “We would invite anyone who questions the value of Dreamers to please come meet some of our students.”

The deadlines to apply for the two types of scholarships offered by TheDream.US are Jan. 23 and March 1.
